2 Claims.

This invention relates to an improved grease retainer with reenforced diaphragm, and this application constitutes a division of an application for patent on Grease retainers by these same inventors filed January 2'7, 1933, Serial No.

653,820. A particular use of the invention is to form a seal about the rear axle of an automobile but it may be used in other installations without departing from the purview of the invention.

One object of the invention is to provide a novel grease retainer which is efiectively reeni'orced so as to prevent distortion thereof during installation and use.

Other objects are to provide agrease retainer embodying a part held in constricted relation about a shaft and to so arrange this part that it may be used alone or in combination with other packing, and an ancillary object is to retain this part and the other packing with it which may be Selected embodiments of the invention are illustrated in the accompanying drawing wherein Fig. 1 is a sectional view showing one form of our grease retainer applied to a section of a shaft and mounted in a housing;

Referring to the drawing and more particularly to Fig. 1, .the'packing comprises a ring made of leather or other suitable material having a tubular portion 1 to engage the periphery of a shaft 8 and a radial portion 9 securely held against rotation in the shell Ill. The peripheral edge of the radial portion of the packing is armored with a binding II which is preferably made of metal in the form of a ring having an annular groove 55 opening inwardly to receive the peripheral edge of the packing. The armor binding is pressed upon the packing to hold it snugly and tightly to prevent the passage of grease or oil between the edge of the packing and the binding and also to prevent the packing from moving rotatively in 5 the binding. One edge l2 of the binding is bent inwardly into the packing to rigidly secure the binding on the packing. A reenforcing ring or washer I 3 is secured against the outer side of the radial portion E2 of the packing and extends over 10 that portion of the packing where the radial portion merges with the tubular portion. The side of the armor binding is offset as at M to secure the washer reenforce to the packing. Moreover, the offset portion M provides a shoulder 15 in the i5 armor binding against which a flange It on the shell Ill is abutted. When the armor binding ii is forced into the shell to be seated therein adjacent one end thereof, a coil spring 18; is arranged about the tubular portion 1 of the packing 20 to hold the tubular portion of the packing in snug engagement with the periphery of the shaft to prevent passage of grease or oil. A reenforcing ring 49 is provided which has an inturned flange 20 at the inner end thereof that engages the inwardly disposed face of the armor binding M. The ring 19 also includes a side M which encloses one end of the shell ill and which retains the spring H3 in the shell. A shoulder 22 is formed in the side 2! at the juncture thereof with the periphery of the ring l9 and a flange 23 on the shell in is engaged with this shoulder. Thus the flanges l6 and 23 on the shell serve to effectively clamp the armor binding l I and the ring l8 in the shell. 5 The armor binding H is pressed into the shell It with suificient force to insure a tight fit between the binding and the shell to thereby prevent rotation of the binding and the packing relative to the shell. The ring l9 effectively reenforces 40 the shell so that it will not be distorted when a tubular member is engaged therewith to drive the retainer into the housing in which it is mounted.

In the form of the invention shown in Fig. 2, a packing comprising a ring made of leather or other suitable material has a tubular portion 1a to engage the periphery of a shaft 8a and a radial portion 9a. securely held against rotation in the shell Illa. The peripheral edge of the radial portion of the packing is armored with a binding Ha similar to the binding II and including an edge l2a bent inwardly into the packing to rigidly secure the binding on the packing. Another packing such as a ring 24 of cork or other suitable innately resilient material has a binding 25 on the periphery thereof which includes side walls 25 and 21 and the inner edge of the side wall 21 is bent into thering to rigidly fasten the 5 binding on the ring. The ring 24 is mounted in the shell Illa at the end thereof opposite the end at which the armor binding Ila on the flanged packing is mounted.

A reenforcing ring I 9a is interposed between the bindings I la and 25 and includes an inturned flange 2011 which engages the inwardly disposed face of the armor binding Ila. The ring I9a also includes a side 2| a which engages the inwardly disposed side wall 21 of the binding 25 15 and which also retains the' coil spring Illa in position to constrict the tubular portion ml of the flanged packing into tight leak-proof engagement with the periphery of the shaft 8a. A flange I 6a at one end of the shell Illa engages the armor 20 binding I I a. and a flange 23a at the other end of the shell engages the outwardly disposed side wall 26 ofthe binding 25. Thus the shell Illa. holds the flanged packing, the innately resilient packing, and the reenforcing ring in assembled rela- 2 tion in a unit structure.

In Fig. 6 a further modified form of the inven tion is shown and herein a packing comprising a ring made of leather or other suitable material has a tubular portion Ib to engage the periphery of a shaft 8b and a radial portion 9b securely held against rotation in the shell Illb. The peripheral edge of the radial portion 9b of the packing is armored with a binding II b similar to the binding Ila and connected to the packing in the same manner as the binding Ila is connected to the radial portion 9a. A reenforcing ring Iiib includes an inturned flange 20b and a side 2"; which retains the coil spring I8b in constricting position about the tubular portion Ib to urge the 40 same into tight engagement with the shaft IBb.

Suitable packing is positioned on each side of the flanged packing and the reeniorcing ring I9b and in the present instance. a ring of felt 28 is provided which has a binding 29 thereon includ- 45 ing sidewalls 30 and 3|, the free edge of the wall 3| being bent into the packing ring 28 to secure the binding 29 thereon. The wall 3| is engaged by the side .2 I b of the ring I917.

The packing on the opposite side of the reen- 60 forcing ring I91) and flanged packing consists of a ring 32 of cork or suitable material having a binding 33 thereon which includes a side wall 34 and a side wall 35. The free edge of the side wall 35 is bent into the ring 32 to secure the binding 55 on the ring. The wall 35 is engaged with the side wall of the binding Ilb. A flange. lib at one end of the shell I b engages the wall 34 and a flange23b at the other end of the shell engages the wall 30. The binding Ilb is pressed into the 60 shell IOb to be held against rotation therein and the flanges at the ends of the shell force the hindings 29 and 33 and the ring I 9b inwardly and securely lock the packings in assembled relation in a unit structure. Y A 65 A still further modified form of'the invention is illustrated in Fig. and herein two packings are provided comprising rings made of leather or other suitable material and having tubular portion Ia and Ice to engage the periphery of the IOshaft 8c and radial portions 90 and Sec securely held against rotation in the shell Illc. The peripheral edge of the radial portion 90 is armored I with a binding Ilc substantially similar to the binding Hm. The periphery of the radial portion 75 Ice is armored with a binding @1911 8 8180 substantially similar to the binding I la. A reenforcing ring l9cc includes an inturned flange 2000 which engages the binding He that is arranged at one end of the shell I 00. The ring I9cc also includes a side 2Icc which is engaged with a side of the binding a. Another reenforcing ring Iiic is provided at the end of the housing opposite the binding 90c and includes an inturned flange 200 which engages the side of the binding IIc opposite that engaged by the side 2lcc. The ring I90 also includes a side Zlc which encloses one end of the shell and retains a spring I 80 in constricting relation about the tubular portion He. The side 2Icc retains a coil spring I8cc in constricting relation about the tubular portionlcc. A flange I60 is provided at one end "of the shell I00 and a flange 230 is provided at the other end of the shell. The bindings Ilc and Ilcc are pressed into the shell I00 and these bindings and the reenforcing rings lie and i900 are held in assembled relation in a unit structure.

In the forms of the invention shown in Figs. 1, 2, 5 and 6 the tubular portions of the packings are constricted onto the shafts by coil springs. In Figs. 3 and 4 modified forms of the invention are illustrated and herein the tubular portions of the packing are urged into leak-proof engagement with the wall of the housing surrounding the shaft.

In Fig. 3, the shaft 8d is journaled in a housing 35 and in this instance a shell Illd is provided which is secured on the periphery of the shaft 8d. The packing includes a tubular portion Id and a radial portion 9d. The peripheral edge of the radial portion of the packing is armored with a binding lld which is preferably made of metal in the form of a ring having an annular groove opening outwardly to receive the peripheral edge of the packing. The armor binding is pressed upon the packing to hold it snugly and tightly and to prevent the passage of grease and oil between the edge of the packing and the binding and also to prevent the packing from moving rotatively in the-binding. One edge In of the binding is bent inwardly into the packing to rigidly secure the binding on the packing. In this form of the invention, the peripheral portion of the binding is narrower than the inwardly disposed part thereof and this is accomplished by offsetting the free edge of the side wall 36 of the binding, and this oflset is suflicient so that when the flange lid on the shell Iild is clamped over into engagement with the binding l I d this flange and the offset portion of the wall 36 are in substantial alignment. The binding (1 is pressed into the shell Illd to. be held against rotative movement therein and is disposed at one end of the shell Ind. A reinforcing ring Iiid includes an inturned flange 20d which engages one side of the binding Ild. The side 2Id of the ring Iild is dished as at 31 so that when the flange 23d on the shell Illd is bent over into engagement with the dished portion of the side, this flange and the remaining portion of the side 2Id are in substantial alignment. The side 2Id holds the coil expansion spring I8d against displacement from the shell and the spring Ild acts on the tubular portion Id to force the same into tight leak-proof engagement with the adjacent surface of the wall of the housing 55.

In Fig. 4 a modified form of the invention is shown which is an adaptation of the forms of the invention shown in Figs. 2 and 3 that is to say, the packing includu a tubular portion 1e which is forced into engagement with the adjacent wall of the housing 35c .by a coil expansion spring I 8e. The packing includes a radial portion 96.

ing lie and the binding He is positioned at one end of the shell Hie. The ring We includes a side 2 ie which retains the spring we in the shell. An innately resilient packing such as a felt ring 38 is provided which has a-binding 39 thereon that includes a side it that is engaged with the side He. The binding 39 also includes a side M which is dished as at 42 adjacent the periphery of the ring 39 to receive the flange 23c on the shell We, the shell also having a flange ite which engages the binding He. The bindings He and 39 are preferably pressed into the shell We and the shell Hie is secured on the periphery of the a shell and provides agrease and oil tight shell.v

The packing ring may be used in connection with innately resilient packing which may be disposed on one or both sides thereof and preferably the innately resilient packing is armored in the same manner asthe radial portion of the packing ring and the armor binding on the innately resilient packing is also tightly engaged with the shell with which it is mounted. The flanges at the ends of the shell hold the packings in assembled relation within the shell and one or more reenforcing rings is interposed between the armor bindings on the-packings and serve to prevent collapsing of the retainers particularly when they are being driven into position. I

We have illustrated several different forms of the invention but it is to be understood that the inventioncan be embodied in other forms and while we have shown the innately resilient packing as being cork and felt and in each instance have illustrated one or the other of these materials it is to be understood that these materials might be interchanged or other materials might be substituted therefor, the choice of materials being dependent chiefly upon the usage to which the retainer is to be put. We have also illustrated certain details of construction but it is to be understood that the invention is susceptible of variation and modification and we therefore do not wish to be limited to the precise details set forth but desire to avail ourselves of such changes and modifications as fall within the ambit of the following claims.

We claim:

l. A grease retainer comprising a shell, a packing ring having a tubular portion to receive a shaft and a radially extending portion, an armor binding enclosing the marginal edge of the radial 1 portion of the packing and engaging the shell at one end thereof, a reenforcing ring interposed between the other end of the shell and said armor binding, annular countersunk portions adjacent the outer rims of the armor binding and the rebinding fastening the reenforcing member in position,. and a reenforcing ring interposed between the radial portion of the packing and the other end of the shell, the reenforcing ring being offset adjacent its periphery to receive the juxtaposed inturned edge of the shell and provide a smooth face for the retainer.
